Abstract:
A gas chromatograph controlled by a pair of microprocessors to have improved thermal maintenance and process operation. The microprocessors are operable to run independently of each other, with one microprocessor controlling heaters and other control devices and the other microprocessor running a graphical user interface. The two microprocessors are separated by a gas chromatograph assembly that includes one or more separation columns.
